The continent of Antarctica is located almost entirely inside the Antarctic Circle and has a permanent layer of ice. Beneath this icy layer there is a great amount of minerals, such as oil, iron and coal. In some areas, the thickness of the layer of ice can reach 3,700 meters. As a consequence, Antarctica is the continent with the highest mean elevation.
Antarctica has a scanty flora, but a rich fauna, including many species of fish, birds and mammals. It has no permanent human population and is ruled by international treaty. Today, there is about 27 nations with research stations settled in the continent.

About Polar Aurora
Polar aurora is a luminous phenomenon that occurs when gases from higher layers of the atmosphere are bombed by solar particles. Then, these particles are affected by the terrestrial magnetic field. The aurora usually happens during solar eruptions.
Polar aurora can be australis (near South Pole) or borealis (near North Pole).
